In the present invention, a 2-4 level shear pump is preferably used in the flow pipeline for raw oil and catalyst which are thereby dispersed and mixed at about 2000-5000 turns/m. Thereafter, the ,sulfuration, of catalyst in the mixed materials is completed using gas containing hydrogen sulfide at the temperature of about 100-180° C.

Hydrogen sulfide is the chemical compound with the formula H 2 S.It is a colorless chalcogen hydride gas with the characteristic foul odor of rotten eggs. It is poisonous, corrosive, and flammable. Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic digestion ...

ZnS/CuS nanotubes are synthesized by using ZnO nanorods as the precursor, followed by ,sulfuration, and subsequent cation exchange reaction. The deposition of CuS on ZnS nanotubes are confirmed by EDS analysis, XPS and UV-Vis diffuse reflectance spectroscopy. HRTEM images clearly display the heterojunctions between ZnS and CuS nanoparticles.
